Topic 8.5: Community Ecology
Learning Objective: 8.5.A
Describe the structure of a community according to its species composition and diversity.
Essential Knowledge: 8.5.A.1
The structure of a community is measured and described in terms of species composition and species diversity. RELEVANT EQUATION Simpson’s Diversity Index— Diversity Index = -∑ (n/N)^2 where n = total number of organisms of a particular species N = total number of organisms of all species
Learning Objective: 8.5.B
Explain how interactions within and among populations influence community structure.
Essential Knowledge: 8.5.B.1
Communities are groups of interacting populations of different species that change over time based on the interactions between those populations.
Essential Knowledge: 8.5.B.2
Interactions among populations determine how they access energy and matter within a community.
Essential Knowledge: 8.5.B.3
Relationships among interacting populations can be characterized by positive and negative effects and can be modeled. Examples include predator/prey interactions, cooperation, trophic cascades, and niche partitioning.
Essential Knowledge: 8.5.B.4
Competition, predation, and symbioses, including parasitism, mutualism, and commensalism, can drive population dynamics.
